Guaranteed PDF Decrypter v3.11.Retail-EAT

PDF security overviewThe standard PDF protection can have two different passwords: a document open password and a permissions password. When a document open password (also known as a user password) is set, anyone who tries to open the PDF must type in the password. When a permissions password (also known as a master or owner password) is set, recipients don't need a password to open the document, but they must type the permissions password to set or change the restricted features. PDF security supports encryption with 40, 128 and 256 bit keys.
